Abstract: A passive-matrix display device has rows (2) of pixels (Pij). A row driver (8) selects sub-groups of the rows (2) to obtain multiple row addressing. Each sub-group has a particular number (p) of the rows (2). In each frame period (Tf) the sub-groups are selected a number of times equal to the particular number (p) at different select instants (ti). The multiple row addressing is based on a scheme defined by a function matrix (FM) which has orthogonal functions (Fi(t)). The columns of the function matrix (FM) represent the orthogonal functions (Fi(t)) at the select instants (ti). The function matrix (FM) is changed such that each one of the columns has at least two non-zero elements (?1,1) and at least one zero element (0).
